'ro ALL WHoM v1T, MAY ooNoERN;

` 'BeV it known that I, HARVEY E LEMING,of Vienna', in the county of Warren, and State of New Jersey, have invented unewand useful Improvement inA Boring-Muchinos;` and I do hereby deelarethc following to-bo a full, clear, andexaet description of the same, reference benghad to the accompanying drawings, which are i made a part ofvthis specification. i l f l The subject of this inventionis a 'boring-machine, havingan auger mounted vonV a stationary frame, and a compound carriage', of which th'efone part-has a motion parallel with the axis of the auger, to feed the stuff 't the action thereof, while the otherhas also a motion at right angles to that of the.foru 1er, to bring tho-diiferent' parts to be 'perforated successively in line-With theauger. .The carriage whose motion is connedfto parallelism with the anger fis the feeding-carriage, the 'otherbeing the adjusting-carriage. 4

Tofaclitate and insure the more perfect operation of the machine, I have-a-pplied a vstop to limit'the motion of the hand-leverpvhiehAaetuates the adjusting-carriage,- soasto arrest the adjustingsearriageat regular interv vals, for the purpose of `,boring 'the holes at regularvdistances from eachother; but, as the auger and compound carriage are separate from andA independent of'each other, and theadjusting-'carriage movableindependently of l' as wellies simultaneously ivith the feeding-carriage, the adjusting-carriage maybe moved byione or a succession 'of impulses, thus enabling the-holes to be bored at'irregular. as well as regular intervals.

Figurel is a.V perspective View of my improved boring-machine. Figures 2 and 3 are views of detached parts, hereinafter referred to.

Similar letters of reference indica-te corresponding parts in theseveral figures.

In the`drawings, A may represent aV strong leg-supported rectangular frame, upon and at oneside of which isi-permanently xed' the housing B of the bearings, which accommodate the spindle'of the auger G.- lThis auger may be rotated Vby a band fromia horse-power, applied to .the pulley C.A This is a very desirablemeans for operating the auger, but the same would not be available ifthe auger did not maintain oneposition;

D is `the feeding-carriage, suitably supported and guided upon the frame A, to enable it to be moved toward or away from thea'ug'er C, parallel thereivith, but in no otherdireeti-on, in operation. n i

E is the adjusting-oarriage,` mounted upon the carriage D,and susceptible of a slidingl motion at right angles'to the-anger, as well'as receiving motion toward and'away from the: latter simultaneously withv the feeding-carriage.

E are knees, andflil2 E2 a'r Vrigidly inthe proper position'. t

p yE3 is a har, tix-ed tothe nppereide of one of ,the side-bars ot'- the carriage E, andhavin'g upon vits upper surface n series of shoulders, formed in pairs, ee, e e', Ste., the shoulders of each pair, aswell .as the pairs thcxnsjelvemrbeing at a uniform distance apart'. I I i t The log having heen brought tothe desired position bythe adjustment of the earriage E, the latter, together b 'with the earriage D, is ni'oved up to the auger by'means of the` lever F, having its fulcrunl atnpon the frame A,.and attached-to thecarriage through the medium of the arm'sF" F', (se-e fig. 2.) 4:By this lever, both oar riages are also retracted from the auger when a hole hasbeen bored.

. 4HH is an angular lever, whose upright part H"(see fig. 3) is pivotedfat'g to a bar, G, pendent from the earl riage D, and carries a feed-hand,h,`whieh`aets upn the shoulders e e,4&c as the lever H H" is vib'rated, and thus gives thatvmotion to the carriage E which brings the different parts ofthe login line with the auger. The shoulders of each pair, say e e,space the two holes which determine the length of a-mortis'e, in the V:formation of which the boring isfthe preliminary step. The vibrating motion of the lever H Hfun'de'rwhich the carriage E is propelled, is limited byl the fixed stop-pin J, projecting from Athe carriage D, so that the lever, by-a single stroke, cannot be madeto'propel the log beyond a position in which-the shoulder against which the feed-hand bears is in line with the auger. Thus, the'first hole of a pair havingibeen bored, one motion. of the lever H H and of the feed-hand h prop-els the carriage E to an extent equal to the distance between the two shoulders of that pair. f In order to engage one of the shoulders efe succeeding'l pair, say e e', the lever H H has to be f `retrarlsterlto an extent borrespending with the distance between the pairs, 'or between the' mortises, and then,

'when the propellingfmotion is given to lever, it propels the carriage and log a distance corresponding with elogs, applied to the adjusting-.carriage E,.for the purpose of holding the log that to which the lever iras retracted, the log being stopped in proper position for the boring o the first hole of' the new mortse by the contact of the impelling-lever with the stop J.

Y It is obvious that, by advanceing the feeding-carriage D to the auger C as often as the adjusting-motion-oi` the carriage Eis arrested, the holes will be bored in` the post at points accurately corresponding with the shoulders on the adjusting-carriage. It 'is also manifest that, by continuingr to vpropel the adjusting-carriage while the feeding-carriage is akt rest, any number of the shoulders may be skipped, and hence the holes may be bored at irregular or -yariouly-spaced points. v

Having thus described my .invcntionfwliat I elaiin as new, and desire to 'secure by Letters Patent, is With the stationary auger C, the carriages D and E, moving laterally and horizontally, the carriage E being movable simultaneously with andalso independently of the carriage D, all constructed and arranged to 'operate substantially in the manner and for the purposes as set forth.
